Blue Dragon Nudibranch (Glaucus atlanticus) is a sea slug reaching 3 cm in length with serrated teeth. They consume, in their entirety, larger sea creatures, including the poisonous Man-of-War Jellyfish. While eating the jellyfish, the Blue Dragon selects and stores the most venomous nematocysts from the jellyfish for its own use, resulting in a more powerful and deadly sting than the Man o' War. It spends most of its time float\ing upside down on the surface tension of the ocean.
